SPECIFICATION forming part of Letters Patent No. 234,078, dated November2, 1880. Application filed September 15, 1880. (No model.)

To all whom it may concern Be it known that I, THOMAS SHARP, of FortYates, in the Territory of Dakota, have invented certaiu new and usefulImprovements in Window-Sashes and their Frames, of which the followingis a specification.

My invention consists, first, in a window having a sliding sash orsashes with horizontally and downwardly beveled stiles, and alsohorizontally and downwardly inclined stops, whereby a wedging fit issecured between the sash or sashes and the stops when the sash or sashesare closed and a free sliding movement permitted while the sash orsashes are being opened; second, in a window having a lower sashprovided with stiles beveled horizontally and downwardly, and with anextension on its upper rail, which is beveled, an upper sash providedwith a beveled extension on its lower rail similar to that on the lowersash, and side stops beveled horizontally and inclined downwardly tocorrespond to the stiles of the lower sash; third, in a window whichcomprises in its construction sashes having horizontally and downwardlybeveled stiles, a frame having horizontally beveled and downwardlyinclined side stops, 2. sill with beveled stop, beveled rails on thesashes, and packing-strips,whereby, when the sashes are closed, awedging packed joint at the sides, bottom and parting rail of the sashesis secured.

In the accompanying drawings, Figure l is a vertical central section ofmy improved window. Fig. 2 is an elevation of one of the inner verticalsash-stops. Fig. 3 is a horizontal section in the line as a: of Fig. 1.

Similar letters refer to similar parts th roughout the several views.

A represents a window-frame B, the upper, and O the lower, sash. Theupper sash, B, is fixed between a center stop, D, and outer stop, E, ofordinary construction, and rests upon a projecting portion, F, betweenthe center and outer stops. The lower rail of the upper sash, B, has aninward upward beveled extension, 11, which fits an outward downwardbeveled extension, c, upon the upper rail of the lower sash, O. Thebeveled extension is provided with a covering of list or other suitablematerial, G, which serves to render the joint between the extensions b 0air-tight when the lower sash is moved down.

The outer bearing portions of the stiles of the lower sash are beveledoff horizontally, as at c, and also vertically, the vertical bevel beingin a downward direction, as at 0 Fig. 1. The two inner side stops, H,are beveled 0E horizontally, as at 71', and are inclined vertically, asat h, the said bevels and inclines coinciding with the horizontal andvertical bevels upon the stiles of the lower sash. The inclined sides hare covered with list G, or' other suitable material, to the height ofthe lower sash, whereby an air-tight joint is effected.

The sill a of the frame is provided with a stop, a, which is beveled offor outwardly inclined, and in frontof which a strip of list, G isfastened to the sill. The lower rail of the lower sash is beveled off,as at 0 in accordance with the beveled stop a. of the sill, and itsbottom face, 0 rests upon the list Gr when the sash is moved down.

The end portions of the beveled stop a are provided with a list coveringor packing, as at G, against which the beveled portion 0 of the lowersash bears when the sash is down.

When thelower sash is moved down upon the window-sill all the beveledand inclined portions of the window sash and frame will meet and thelower sash become firmly wedged against the upper sash,the verticalstops, and the lower stops of the sill, and neither draft nor cold airwill find their way into the room. When the lower sash is raised itbecomes at once free and easy to move, as its play between the stopsincreases the higher the sash is raised.

1 have shown and described a rigid upper sash but it is evident thatwhen a movable upper sash is used the upper sash can be constructed in amanner similar to that of the described lower sash, with thisdifference, that the vertical inclines of the stops must wedge upwardly.

The construction of my window is so simple that the ordinary or generalfeatures of the window frame and sashes are not interfered with, andtherefore I can apply my improvements on old windows without cuttingdown and weakening the sash or the window-frame, as is required in otherinventions for similar purposes, and with new windows the fullillumination-space in a given-sized sash is retained Withoutwidening thesash and windowcasing frame, which is not possible with those planswhich employ beveled tongues and grooves for effecting the objectsherein set forth.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is-

1. In a window, the combination of a sliding sash having horizontallyand vertically beveled stiles, as at 0 c and horizontallybeveled 3 andvertically-inclined stops, as at 11 h, to

] match, substantially as and for the purpose set forth.

2. The lower sash, (J, having a beveled extension, c, on its upper rail,and an upper sash, B, having a similarly-beveled extension, I), incombination with the stiles, beveled as at 0' c and inclined and beveledstops, as at h h, substantially as and for the purpose set forth.

3. The packings G G G G, in combination with the wedging-surfaces b, c,c, h, h, a, 0 and a of the frame A, stops H, and sash G, substantiallyas and for the purpose set forth.
